IMPROVEMENT IN CARRIAGE-WHEELS.

Specification forming part of Letters Patent No. 129,686, dated July 23,1872.

Specification describing certain Improvements in Carriage-Wheels,invented by SAM- UEL E. SHUTE and WILLIAM G. STARR, both of Richmond,county of Wayne, State of Indiana. Our invention relates to theconstruction of a carriage-wheel, wherein the hub is constructed byfirst providing a metallic shell having mortises in it, into which thespokes are driven. The shell also extends back to the rear end of thehub, and has a screw cut in it, into which a wooden core is screwed,thus forming the rear end of the hub. The shell also extends forward infront of the spoke-mortises, and is made in slightly taper form toreceive a wooden core, which is driven or pressed into it from the rearend. I

Figure 1 is a cross-section, showing the tenons E of the spokes and thedivisions G between the mortises. Fig. 2 is a longitudinal section,showing the shell B as constructed with the wooden core A screwed intoits rear end and the wooden core H driven into its front end. 7 i p B isthe metallic shell, cast in one piece, consisting of the shell B,flanges O, and connec tions or divisions 0, between the mortises. Theseconnections or divisions are made diamond shaped, the longest faces ofthe diamond being parallel with the line of the spoke-tenons, the outeror short faces forming the shoulders upon which the spokes are arched.The outer end of the shell is made slightly tapering on the inside,being smaller at the point than at the spoke-line, the woodencoreHbeingpressed or driven in from the. rear end. The core A is thenscrewed into the rear end of the shell even with the spoke-line at theback end of the mortises in the shell. The inner end of the core A ismade slightly cone-shaped, to

compress and firmly grasp the lower ends of the spoke-tenons edgewise.The rear or outer end of the core A is slightly chamfered, the rear endof the metallic shell being closed in upon the chamfered end of the coreA, thereby permanently holding the core in place in connectionwith'thescrew. The front or outer end of the shell B is also fitted andclosed down in like manner into a chamfer, P, on the front core H.

After the hub is formed as described, the spokes are driven.

What we claim, and desire to secure by Letters Patent, is-

1. The shell B, cast in one piece, in combination with the wooden coresA and H, as specified. I

2. The core A, screwed into the shell B, having its inner endcone-shaped, as described.

3. The metallic shellB, upset" at the ends into or upon the wooden coresA and H, substantially as and for the purpose specified.

4. The metallic shell B, cylindrical and screw-threaded in rear of thespoke-mortises, and tapering in front thereof, in combination with thecylindrical and screw-threaded core A and tapering core H, substantiallyas and for the purposes specified.
